dde853a4ad Small change to stack checks in unoptimized code.
The stack checks include a loop nesting depth encoded in the code stream
after the call to the stack check stub.  Change the code to jump around this
instruction as well as the call when the stack check is OK.

2957881a26 Misc debugger enhancements and bug fixes.
1. Added gdb style debugger commands (and their shortcuts) for d8.
These include:
- s[tep] : step into the current statement.
- s[tep]i[n]: step into the current statement with the minimum step.
- n[ext] : step to the next statement.
- fin[ish] : step out of the current function.
- cond : setting conditions on breakpoints.
- d[elete] : deletes breakpoints.
- en[able]|dis[able]: enables/disables breakpoints including
exception breakpoints.
- ignore : ignores a breakpoint for a specified period.
- inf[o] ar[gs] : info on arguments of the current function.
- inf[o] lo[cals] : info on local vars of the current function.
- inf[o] br[eakpoints] : info on breakpoints.
- l[ist] : similar to source, but allows the user to continually
dump subsequent lines of source code either in the
forward or backward direction.
- quit / exit / disconnect : terminates the remote debugger
session.

NOTE: Active breakpoints will automatically be disabled when
the remote debugger detaches. This allows v8 to continue to
run without worrying about a loss of a debugger session.

2. Added support for breaking the debugger by simply typing ENTER.
The break command is now optional.

3. Once the debugger is broken, the user can now just type ENTER
to repeat the last command. This is useful to functionality that
needs to be invoked repeatedly e.g. step, list.

4. Added more verbose descriptions in d8's help.

5. Fixed a line and column number offset bug in the listing of breakpoint
line and column numbers.

6. Added a gc command to allow GCs to be requested from the debugger
interface. The plumbing for requesting different types of GCs is
there, but the underlying implementation currently only triggers a
full mark-compact GC. The command also returns the before and after
sizes of the heap.

7. Added trace json, and flags commands that are not published in help.
trace json is used for tracing the debugger packets send from and
received by d8. flags is for setting v8 flags. These are useful for
people debugging v8 itself, but not necessarily users of v8.

8. Added the ability to enable and disable break on all / uncaught
exceptions in to d8.

9. Added a fix to prevent the Debugger Agent from being re-instantiated
if one already exists.

10. Added the ability to filter results of the script command by matching
text or numbers on the results.

11. Added v8 flags to enable/disable the sending of debugger BeforeCompile,
AfterCompile, and ScriptCollected events.

12. Fixed some undefined value bugs that resulted in v8 or the debugger
failing.

13. Added a few minor WEBOS__ customizations (analogous to ANDROID
customizations).

2b7596a516 Instanceof slow case bind is incorrect.
Currently, the bind for the slow label is after the pushing of the
args registers which renders the args pushing dead code because there
is a Ret preceeding it. The comments also imply that the arg pushing
should be part of the InvokeBuiltins tail call.

9a096e643a Fix an bug in deoptimization after polymorphic calls in effect contexts.
For polymorphic calls (also loads and stores) we construct a type switch
graph that has a basic block merging all the variants.  There is an
environment simulation before the goto at the end of all the predecessor
blocks.  This simulation is used to define the environment on entry to the
successor block, and captures the return value of the call.  In effect
contexts, this value should not be present in the environment.

The fix is to use the AST context to decide whether to have this value in
the join node's environment at all.

7311e10fdb Optimize instanceof further
If the instance of is performed against what is beliwed to be a constant global function inline the instance of check and have the call to the instanceof stub in deferred code. The inlined check will be patched by the instanceof stub when called from deferred code. This is indicated by the lithium instruction LInstanceOfKnownGlobal.

To help the patching the delta from the return address to the patch site is placed just below the return address in the edi slot of the pushad/popad ares. This is safe because the edi register (which is pushed last) is a temporary for the lithium instruction.

As the instanceof stub can call other JavaScript an additional marking for saving all double registers have been added.

Also tweaked the instanceof stub to produce true/false objects instead of 0/1 for the case with deferred code.

f95f295dcb Add use_system_v8 option to gyp (off by default),
